' INKING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 264,088, dated September 12, 1882.

Application filed October 24, 1881. (ModeL) l 0 all whom itmay concern:

Be it known that I, WILLIAM LIGHTFOOT, Jr., of the city of Toronto, county of York, Province of Ontario, and Dominion of Canada, have invented a new and useful Inking Apparatus for Printing-Presses, of which the following is a specification.

My invention relates to what are known as disk printing-presses and the object of such invention is to furnish a continuous and even supply of ink to such printing-presses. I obtain this object by the mechanism illus-' trated in the accompanying drawings.

Figure l is a perspective view, showing transfer-roller a revolving against and distributingink, with cylinder b and supply-roller a coming up disk A for a supply of ink from cylinder 12.

Fig. 2 is a perspective view, showing supply-roller a revolving under and receiving a supply of ink from cylinder 1) after having pushed transfer-roller 0 against fountain'roller F. The carriage O carries the type-rollers B B and supply-roller a down and up over the form on press to cylinder 1), (see Fig. 2,) where carriage O or the wheels or collars of supplyroller a come in contact with projecting arm L, attached to frame I, and press transfer-roller 0 back against fountain-roller F for a supply of ink. (See Fig. 2.) The said transferroller 0, as it swings back from the cylinder Z), causes fountain-roller F to partly turn round, which draws the ink from the fountain roller F. This turning is caused by the arm L be- G presses transfenroller 0 back to the fountainroller .1 supply-roller a ascends by means of tracks E E and comes in contact with cylinder b, which is revolving sufficiently fast to give supply-roller a one revolution during an impression of the press. The result 0t such contact is that supply-roller a receives a supply of ink finely distributed over its entire surface, which, on its return, distributes it over disk A, and by means of wheels or collars larger than those of the type-inking rollers B B is carried over the form without touching the type. Transfer-roller c, as soon as relieved of the pressure of carriage C, swings back to cylinderb, where the ink it has-received from fountain-roller F is distributed by means of their revolving together. Cylinder b is revolved by means of pulley G and belt Kfrom main shaft of press. The frame D for holding the inking apparatus is attached by bolts to the frame of the press under the disk.

I claim- The combination of the carriage 0, bearing the inking-rollers and the supply-roller, the raised way E, the elevated distributing-cylinder b, and the transfer-roller c, mounted on vibrating frame I, provided with projections L, all substantially as described.
